Q.Gladiola Zone 9
I live in Arcata, CA Zone 9; our garden has clay soil type. We have an extra Yard that’s down hill, shown in the picture; it’s still on berry bushes madness. I’m planning to clear that out, then I found Gladiola bulb they sell it on our local market. Since that, I googled what is Gladiola and look on how to growing them, in love.
Will Gladiola Grow on clay soil? The soil is clumped and not easy to loosen up, but I assure you that I dug 1 gallon of soil to put in a Schefflera plant, and they’re doing fine.
Will Gladiola will be fine to plant in clay soil type?
Thank you
